Deploy your Flask app to Firebase Hosting
Step-by-step deployment help for Flask apps on Firebase Hosting. We fix Flask-specific deployment issues, configure Firebase Hosting, and get your app live. From $19.
Flask issues we fix before deploying
Common Flask problems that affect Firebase Hosting deployments.
Debug mode in production
Flask's built-in debugger left enabled in production, exposing an interactive console that allows remote code execution on the server.
Hardcoded secret key
SECRET_KEY set to a default or short string like 'secret' instead of a cryptographically random value loaded from environment variables.
No CSRF protection
Forms and state-changing endpoints without Flask-WTF CSRF tokens, enabling cross-site request forgery attacks.
Running with flask run in production
Using Flask's development server in production instead of gunicorn or uWSGI, which is single-threaded and not designed for real traffic.
Firebase Hosting deployment issues we check for
Common Firebase Hosting problems that break Flask apps in production.
Firestore security rules allow public read/write
AI tools set Firestore rules to allow read, write: if true for development and never lock them down, exposing the entire database to any authenticated or anonymous user.
Cloud Functions cold start on free Spark plan
Firebase Cloud Functions on the Spark plan have aggressive cold starts and limited concurrency, causing 5-15 second delays on first invocation.
firebase.json rewrites not matching SPA routes
Single-page app routing requires a rewrite rule in firebase.json to send all requests to index.html. AI tools either omit this or misconfigure it alongside Cloud Functions rewrites.
Storage rules expose private user files
Firebase Storage rules generated by AI allow any authenticated user to read any file, rather than restricting access to the file owner.

What Flask issues affect Firebase Hosting deployments?
Flask projects commonly have debug mode in production and hardcoded secret key. On Firebase Hosting, these combine with firestore security rules allow public read/write and cloud functions cold start on free spark plan to cause deployment failures.
